A new document that gives developers an orientation to the basic concepts, terminology, architectures, and design patterns of Cocoa.

The now-retired documents consolidated as chapters in this document are "What Is Cocoa?," "Cocoa Objects," "Adding Behavior to a Cocoa Program," "Cocoa Design Patterns," and "Communicating With Objects." Two new chapters have been added: “The Core Application Architecture on OS X” and “Other Cocoa Architectures on OS X”. In addition, the discussion of the Model-View-Controller design pattern in Cocoa Design Patterns has been greatly expanded.
